Joint transmissions of data in a wireless communication system using a non-orthogonal multiple access transmission scheme

A user equipment configured for a communication in a wireless communication system, the wireless communication system comprising a plurality of user equipments and

• a plurality of transmission/reception points (TRPs), the plurality of TRPs comprising at least a first TRP and a second TRP,
• wherein second order channel statistics for at least one channel parameter between the first and second TRPs and the user equipment are within a certain range,
• wherein the user equipment is configured to communicate with the first and second TRPs using first resources, and
• wherein, for transmitting or receiving data of the user equipment the user equipment is to
• transmit to or receive from the first TRP a first superimposed signal using the resources of the first TRP and comprising a data signal of the user equipment superimposed with a data signal of a further user equipment, and
• transmit to or receive from the second TRP a second superimposed signal using resources of the second TRP and comprising a further data signal of the further user equipment superimposed with a further data signal of the user equipment.

A method for transmitting or receiving data of a user equipment in a wireless communication system,

• wherein the wireless communication system comprises a plurality of user equipments and a plurality of transmission/reception points, TRPs, the plurality of TRPs comprising at least a first TRP and a second TRP,
• wherein second order channel statistics for at least one channel parameter between the first and second TRPs and at least one user equipment are within a certain range, and
• wherein the method comprises:
• communicating with the first and second TRPs using first resources, and
• for transmitting or receiving data of the at least one user equipment
• transmitting to or receiving from the first TRP a first superimposed signal using resources of the first TRP and comprising a data signal of the first user equipment superimposed with a data signal of a further user equipment, and
• transmitting to or receiving from the second TRP a second superimposed signal using resources of the second TRP and comprising a further data signal of the first user equipment superimposed with a further data signal of the second user equipment.

A transmission/reception point (TRP) for a wireless communication system data, the wireless communication system comprising a plurality of user equipments and a plurality of transmission/reception points (TRPs), the plurality of TRPs comprising at least a first TRP and a second TRP,

• wherein the TRP is to transmit or receive data of a first user equipment and data of a second user equipment
• wherein second order channel statistics for at least one channel parameter between the first and second TRPs and the first user equipment are within a first range,
• wherein second order channel statistics for at least one channel parameter between the first and second TRPs and the second user equipment are within a second range, and
• wherein, for transmitting or receiving data of the first user equipment and of the second user equipment, the TRP is to
• transmit or receive a first superimposed signal using first resources and comprising a data signal of the first user equipment superimposed with a data signal of the second user equipment, and
• transmit or receive a second superimposed signal using the first resources and comprising a further data signal of the second user equipment superimposed with a further data signal first user equipment.
